IMPROVEMENT I N HEATlNG-VSTOVES.

Specication forming part of Letters Patent No. 198,007, dated December11,1877; application led May i7, 1877.

To all whom 'it may concern:

Be it known that I, DAVID B. EBERLY, of

Pine Village, Warren county, State of Indiana, have invented anImprovement in Heating-Stoves, of which the following is aspeciiication: My invention relates to the class of anthracite and othercoal stoves which are provided with supply-chambers to feed the firecontinuously; and my invention consists, in the iirst part, in makingthe feeding-cylinder in two parts, telescope style, one part beingarranged to slide on or in the other, and iitted with appliances bywhich it may be raised and lowered, so that its lower edge may beadjusted to different heights with relation to the gratebasket, theobject of this device being to regulate the consumption of fuel andconsequent radiationl of heat by the adjustment of the feed-throat.

In the accompanying drawings, Figure l is a vertical section of ananthracite-stove embodyingmy invention. Fig. 2 is a perspective view-ofthe cone-baske v A is the shell of the stove; B, the conicalgrate-basket, and C the feed-chamber. The feed-chamber is supported fromthe top on collar c, and is fed through cover I).

In place of making the feed-chamber in one piece, I make the principalpart c shorter than usual, and fit a sliding part, c", to it, which Iconstruct with a screw-threaded lug, c'. In this lug an adjusting-screw,E, is fitted, which is suspended from the cover of the stove in themanner shown, and provided with a handcrank, F. By the rotation of thiscrank the height ofthe slide c" may be regulated, and by its adjustmentthe amount of coal exposed the cracking of the cone, and, by reason ofits .l being in two parts, provides for cheap repair. Y

I am aware that telescopic magazines for stoves are not new; but Ibelieve that I am the first to so combine such a telescopic magazinewith the grate-basket of the stove without any intervening throat, thatthe amount of fuel exposed to combustion above the gratebasket may beincreased or diminished by the adjustment of the lower section of themagazine.

The combination7 substantially as specified, of the stationarygratebasket, the Vstationary upper section of the magazine orfeed-chamber, and the lower section thereof, adjustable up and down bymeans of a hand-screw, for regulating the amount of fuel exposed tocombustion above the top of the grate-basket.

In testimony of which invention I hereunto set my hand.

DAVID D. EBEELY.
